A man suffered serious injuries in an electrical explosion in central London which led to a power cut.
Shops were evacuated and witnesses heard a loud noise and saw smoke in Hanover Street, south of Oxford Circus.
The man, in his 60s, is being treated for burns which are said to be life-threatening, after he drilled through an electric cable.
A cordon has been put in place between Hanover Street and Regent Street but power has been restored to the area.
Bus and tube services are not affected.
